Is is possible to bind class properties to mxml components ? E.g.: I have a class A.as with a String property nameValue. What I want to achieve is always having the latest value of a mx:Text component in nameValue.
View 2 RepliesLately i discovered MATE (for Flex development) and was wondering: how do i bind a property in a view (actually a navigatorcontent component) to another property in a class so that they stay in synchronization (meaning that whenever the property in the class changes the property in the view also changes).
So if we have a view called Target.mxml and a property targertProp how do we bind it to the class called SourceClass with property SourceProp?
I would like to bind a variable from my ActionScript to a property of a component that is in a ItemRender. But I always get this error:

Here is my code

<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:solutionItems="com.barco.components.ControlRoomConfigurator.solutionItems.*">

I would like to use the object currentRoom in my ItemRenderer component.

Can't seem to bind to data from within a custom component. I've tried BindUtilis and {} but can't seem to fathom it out. Here's what I've got:
I have a class DataModel which has been made bindable
Within Mainn.mxml I have two components: DataGrid (used for testing) & CustomComponent (which extends Canvas)
When the data within DataModel.somelist is updated the DataGrid reflects the changes but the CustomComponent doesn't appear to.
I was expecting to see the trace (CustomComponent.dataProvider) fired whenever this._dataModel.itemList is changed. [code]...
I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?
Is it possible to access a declared component as an IFactory within an MXML class? I've used this style of declaring factories many times for Skin Parts, but I've never figured out how to access those factories from within the MXML.

<fx:Component id="labelDisplay">

I'm wondering if there is a way I can bind a flex property to flash property?, the flash property is inside a swc file created in flash with the Flex Component Kit for Flash Professional, I can manipulate the flash component as a regular flex component, but I want to bind their properties, is there a way?

I would like to know if it is the same to assign properties to my custom component in its own class, or from the parent document. Here I assign the property bottom in my custom component class:

I've developed a component which is a combination of a few items (canvas, labels, etc...) but when I try to bind it to a variable such as: {stationXML.getItemAt(1).AAA.@value}, it doesnt work. Before I combined all the items in a component, they were all in the main MXML file at which time they worked. Not sure if it matters, but the "stationXML" arraycollection variable is declared inside the file "Station.as".
View 2 RepliesI have a DataGrid component that I would like to update every 5 seconds. As rows are being added to this DataGrid I noticed that every update causes it to reset the scroll bar position to the top. How can I manage to keep the scroll bar at its previous position?
View 4 RepliesI have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.
View 4 RepliesDoes there exist a Flex view component that you could just pass it a custom object with all public fields/properties that it could reflect over and produce a basic UI view using flex components.

I've always just developed my projects in as3 instead of mxml and I usually just setup my application to run a main actionscript file as my main doc root, sort of like how you do it in flash but in flash builder I do something like this:[code] how can I call place a call to that function hitme() within the call_from_outside() function between the <fx:Script> tags?The reason why I'm doing this is because I have some flash swfs that I load into another swf file and I can access the top level public functions of those flash swfs, however the top level of the flash builder/flex swfs is the main mxml file not my fake as3 class root. Of course I should think there is a way for me to access the as3 class methods of the mxml component but for keeping things with the same structure, I can bypass having to modify my loader scripts.
View 1 RepliesI'm new to ActionScript and Flex but I was wondering, when do you create an MXML component and when do you simply code it in ActionScript? Does it matter either way, what are the pros & cons to both?
Does an MXML Component essentially create it's own class when compiled?
I am getting the error: warning: unable to bind to property 'Description' on class 'Object' (class is not an IEventDispatcher)
this is only when the data is bound to a List as an ArrayList, though. I had it in a Datagrid before (just as an Array) and it did not cause any issue. I'm not expecting to be able to bind any data back to the class 'object' not even sure which object exactly it's referring to.
My list data-provider is an ArrayList.. populated by a result event from an SQL query contained in another class:
private function loadDayComplete():void
{
var Meals:Array = _day.MealResults;
[Code].....
The day class I have is a data holder to get all the data (from several tables) for a 24 hour span.. I have classes for each individual datatype for editing them. But I'm not sure do I even need to worry about the warning if I don't plan on editing the values? it completely spams the console though whenever I touch anything, so I really would like to get rid of it. I tried an object proxy as I saw described elsewhere but nothing changed. The text is in label fields right now anyway, which can't even be edited.
I have a label component in a mxml file like below
<mx:Label x="700" y="409" text="Label" id="lble" width="131" height="41"/>

I have a Custom Component that has a couple of Canvas with some background colors assigned to them. Now i have hard coded the colors, i want to move them to an external css file. So i would like to have the css declaration like this :
[Code]...
My question is if i can define custom style names like dividerRightColor and if so, how can i use that value inside my MXML Component? I have seen examples of using them inside Pure AS components.
Is it possible to set a percentage value for the width property of an UIComponent defined in MXML using data binding?
What I try to achieve is something like this (which doesn't work):
<s:Button width="{buttonWidth}%"/>
I know that using percentage for width or height properties in MXML is kind of a hack in the Flex SDK, since they're supposed to accept numerical values only, but since percentWidth and percentHeight aren't available in MXML, I'm pretty stuck =/
I would really like to avoid using code to do such a simple thing, in order to keep my code as clear and readable as posible.
Since there's so much potential pollution within namespaces, particularly with the parser automatically declaring any MXML component with an id to be publicly-accessible using that ID I'm finding it dangerous to use just camelCase for MXML element ids. eg:
[Code]...
In Flash development, a lot of us did this for (automatically) declared stage instances like "mcMyTabBar" or "navMC" or "playPauseBTN". I'm looking for input from the Flex community about this. Am I just overthinking things? All of the related Style Guides and best practices documents I've read on the topic just say "use camelCase for ids, and make sure the id property is the first property". What's your take?
